Abstract
A single-piece elastomeric mount (22) installed over a plurality of openings (15) has a like plurality of reinforcing plates (44 and 46) to permit the elastomeric rib between the plates' edges to flex. The apertures (24 and 26) in the mount can then be aligned with holes (15) in a support (13) having wider tolerances on their end positions. The mount may include two sets of plates - an upper load-distribution set (44 and 46) and a lower wear-reducing set (30 and 32), each set being bonded to the elastomer.
Description
W O 97/10466 PCTrUS96/10572 SINGLE-PIECE MOUNT Wl'l'~l SPLIT METAL PLATES
R~ck~round and Sllmn~ry ofthe Invention This invention relates to the field of elastomeric mounts. More 5 particularly, the present invention is directed to a mount having split plates which increase wear resistance while permitting fl~xing of the mount to permit variations in the support plate's hole spacing to be accommodated.
A concern arose regarding the wear life of a bushing mount being used to support a diesel truck engine. The mount is a cylindrical center-bonded 10 bushing or grommet-style mount which was used in a flanged support that is formed as a casting. A small diameter portion of the mount (the "shank") extends through a hole formed in the support while a larger diameter portion (the "head") rests on the surface of the support. The lower surface of the head was expçrienring conqi(lerable wear as a result of the vibration-induced 15 movement between that surface and the rough cast surface of the support. In ~ ition, test parts developed .qignific~nt cracks at the transition point between the shank and the head. Further the upper surface of the head offered minimal surface area through which to react loads.
The present invention seeks to remedy whichever one of these 20 problems is most serious for a particular application by extending the mount to reach between at least two holes in the supporting member and incorporating a metallic plate into the upper or lower surface to reduce wear.
A problem arose when a single plate was provided that extended between the two holes: in forming the casting, dowel rods are used to position the 2!; grommet-receiving holes in the support. As the molten metal is poured into the casting, the dowel rods can be caused to move within a limited range of poqitionq resulting in non-uniformity in the center hole spacing in the support.The lack of fl~xihilit.y in the mount caused by the wear-reducing plate nece.q.qit~ted the customer to assume the additional expense of m~ hining 30 their part to provide a more uniform hole spacing or resulted in even greater additional costs associated with discarding out-of-spec castings.
W O 97/10466 P~T~US96/10572 To resolve this problem, the flexihility of the present mount is ~nh~nce-l by subdividing the reinforcement plate(s), with each fastener-receiving aperture being provided with its own wear-re(lllrin~ and/or load distributing plate. The elastomer between the surface plates serves as a S fle~nhle spine or rib ~n~hling the center-to-center spacing of the apertures to be ~exed to accommodate the out-of-spec hole spacing in the support. The upper load-distributing plates ~i~ifi~ntly increase the surface area which engages the supported member thereby more widely dist~ibuting the load. For this particular applir~hc n, it is preferred that each aperture be provided with10 a set of both upper load-distributive plates and a set of lower wear-reducingplates, but some applications may require only one of these sets of plates.
Various other features, advantages and characteristics of the present invention will become apparent after a reading of the following specification.

5. The elastomeric mount of Claim 4 wherein said at least two metallic plates of said first set positioned adjacent said lower surface of saidelastomer are each formed as separate stampings, said extruded collar non-engagingly receiving one of said metallic sleeves.
6. The elastomeric mount of Claim 5 further comprising a deformable elastomeric boot surrounding and extending beyond said metallic sleeve, said elastomeric boot being deformable to form a rebound cushion.
7. The elastomeric mount of Claim 6 wherein a thickness of said plate from said second set and said metallic sleeve form a fixed distance between an underneath surface of a bolt head and an opposing surface of a connected nut.
8. The elastomeric mount of Claim 7 wherein said fixed distance between an underneath surface of a bolt head and an opposing surface of a connected nut is generally equal to a thickness normally occupied by a supported member, said elastomeric mount, said supporting member, said elastomeric boot in a fully compressed position, and washer means against which said connected nut seats, whereby said elastomeric boot operates as a rebound cushion against an upward movement of said supported member relative to said supporting member.
